Epidemiological characteristics of central nervous system tumors in children: a 5-year review of 3180 cases from Beijing Tiantan Hospital.

Due to the lack of national data on childhood brain tumors, we used a large nationally representative population sample based on the largest pediatric neurosurgery center in China. We analyzed the data of the past 5 years, reflecting the incidence of CNS tumors in Chinese children to a certain extent, and laying a data foundation for subsequent clinical studies.
